feat(aidd-vcs): recover from scoped commit hook failures

[alexsoyes]

🎯 What & why

The commit skill retries safe, deterministic hook fixes within the current commit instead of stopping at the first rejection.

🛠️ How it works

• Scope stays explicit paths or staged files.
• Retry deterministic in-scope fixes only.
• Stop on ambiguity, scope escape, no progress, or three failures.
• Report SHA, files, corrections, and push outcome.

The public README and catalogs reflect this contract.

🧪 How to verify

• pnpm exec lefthook run pre-commit --all-files --force
• pnpm exec lefthook run pre-push
• Read 03-commit.md.

✅ I certify

• I DO CERTIFY I READ EACH LINE OF THE PULL REQUEST BECAUSE I AM A SOFTWARE ENGINEER, NOT A AI PUPPY.
